The leve system is a perfect foundation for what everyone wants.

First people need leves everyday. 24 hours Leve reset. That takes care of quantity.

Now on to quality. Players want variety. Suggestions:

1.) Survival leves: Player must survive against waves of enemies for a set time.

2.) Exploration: Players must advance to a set position, aggressive mobs make clearing the path difficult.

3.) Battle Regimen tutorial: Low-level Leve where players must complete 10 battle Regimen to complete (include on screen instructions for how to do this)

4.) Escort: NPC must be protected while traveling to a set destination

5.) NM leve Bosses

If Regional Leves were both more consistantly available and more interesting, players would enjoy them more.
